Dataset description

Vertical profiles of carbon dioxide and temperature in Mars upper atmosphere retrieved by the Royal Belgian Institute for Space Aeronomy from diffraction order 165 of the SO channel of the NOMAD instrument on board ESA’s ExoMars Trace Gas Orbiter. These measurements were performed by solar occultation by Mars atmosphere. The temperature profiles are derived from the carbon dioxide density profiles with the hydrostatic equilibrium equation. Those profiles extends from around 140 km to 190 km altitude depending on the seasons at Mars. The corresponding uncertainties, solar longitudes, local solar times, latitudes and longitudes are also provided within this archive.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
